This invention isters.

' An object of relates to I autographic regthis invention is to provide an autographic register by means of which,

forms printed on superposed strips may be kept in registry as the strips are fed through the machine.

A further objectis to produce a device of the character described in which the forms are brought into accurate registry just prior to the moment of inscription.

A further object is to produce a device of the character described, which will be simple in construction and eflicient in operation.

Other objects of the invention will in part be obvious and will in part appearhereinafter.

The invention accordingly comprises the features of construction, combinations of elements, and arrangement of parts, which will be exemplified in the construction hereinafter set forth and the scope of the application of which will be lndicated in the claims. Y p V For a fuller understanding of the nature and objects of the invention, reference should be had to the following detailed description taken in connection with the accompanying drawings, in which: v 1

Figure 1 is a fragmental vertical section through a register embodying. this invention,

Fig. 2 is a fragmentaltop plan view of the same, and

Fig. 3 is a transverse fragmental section along the line III--III of Fig. 2.

In autographic registers where it is desirable to 'producea large number of manifold copies on printediforms, difliculty has been experienced in bringing the forms into registry, and this difliculty is greater as the number of copies is increased. For this reason, although various mechanisms have'been devised, machines which produce satisfac tory alignment with three or four copies have not proven satisfactory where a large number of co ies is employed.

Since t ere is considerable variation in the length of paper strips carrying the printed forms due to shrinkage of the paper, it is attempt tofeed the strips by t desirable to have the feed controlled by operation between the strip itself through the medium of control apertures, such strip being used with a feed mechanism comprising a roll and disc engaging each other in longitudinal alignment with the aperture.

This form of str1 and feed in itself is sufiicient to align printed forms where only a wit an inclined face, has a tendency when entering one of the control apertures to force the control a rtures and hence the printed forms into alignment with each other. This is not always satisfactory, however, since the I pin sometimes damages the ed e of the control aperture which not only oes not cause the alignment, but it also tends to lock the sheets together in an unaligned position. Pins passing through the apertures transverse to the plane of the web are moreover,

ether the strips be in alignment or not. It is not always satisfactory moreover, to

hecontrol apertu'res as this places a greater strain upon the control apertures than they will stand, even iftwo successivesets of control apertures be simultaneously engaged.

The numeral 1 designates a casing, having apt to damage the edge of the aperture,

at one end a compartment 2 for the reception of a multiple strip web supply 3, and at the other end a compartment 4 adapted for the reception of one of the strips after recording. To facilitate insertion of the supply, the end wall 5 of the compartment 2 is pivoted as shown at 6. I

Arranged above the compartment 2 is a tablet 7 over which the strips may be fed by a feeding mechanism, comprising discs 8 cooperatingwith roller 9 to grip the strips between them. The discs may be comparatively narrow and in alignment with feed control apertures in the strip, whereby the feeding of the strips by thediscs ceases when the discs but controlled in position by a projection 16 engages a cam 17. The construction of this cam is such as to release the pin for extension beyond the periphery of the disc 8 at the close of the feeding movement, but is withdlawnto or below the level of the periphery of the disc when the next feeding movement starts.

With the above construction, it will be obvious that the strips will be fed by cooperation of the discs 8 and the roller 9 until the point of contact between them has reached a control aperture, whereupon the feeding will cease. In order to initiate thereafter a new feeding movement, lugs 18 may be provided upon the discs in position to engage the strips at the side of the control apertures, and these lugs are so arranged relative to the stop 12 that they will engage the strips at the time the handle 11 is in contact with the stop.

The strips are preferably provided with forms bearing definite relation to the control apertures and for the purpose of bringing the forms into alignment upon the tablet, there is provided a special aligning mechanism as folows: A shaft 19 pivoted in the sides of the frame for oscillatable movement, carries pins 20 V which have a portion of their surface substan- Should, at this time, one of the strips .be in tially the diameter of the control apertures and which are movable by the rotation of the shaft from a position substantially as shown in Figure 1 where the pins are in a position to engage the control aperturesliin the strips, to a position wherethe apert res are permitted to slide off the pins. To accomplish this result, the pins are carried rigidly by the shaft while the latter is controlled in its position by a stop 21 and a spring 22, the former limiting the movement of the pin contrary to the direction of feed by engaging a projection 23 upon the casing. The spring 22, which is connected at one end to the casing and at the other end to a collar 24, also detachably connected upon the shaft, urges such rotation of the shaft as to bring the stop in contact with the projection.

It is the purpose of this construction to cause the strips to ride over the top of the plns in their substantially upright position until acontrol a rture comes into registry, whereupon the plus enter a control aperture.

advance of the others, the entire pressure of the pins will be exerted upon the advanced str1p, agamst the movement of the feed, thus bringing all the strips intoregistry with each other. A further movement of the strip b the feeding mechanism brings the record S, eets taut upon the tablet.

A still further movement of the strips tilts the pins in the direction of feed against the resistance of the spring 22 until the inclination of the pins has become sufiicient to permit the strips to slide off the top of the pins. To facilitate this tilting action, the forward side of the pins is cut off at an angle as shown at 25. The inclination of the pins during the feeding of the web may be adjusted by altering the position of the stop 21 by loosening the said screw 21' while the strength of the spring against which the strip must operate after the pins have entered the aperture may be adjusted by limiting the position of the collar 24 through the medium of the set screw 24.

Aguide roller 26 is arranged to guide the multiple pl strip as it is fed over the tablet and the ro ler is so positioned as to cause the strip gently to bear down upon the points of the ins 20 during the feeding movement. A gui e rod 27 ma be provided, if desired, over which the strip may be fed, but ordinarily this will not be required.

3 The operation of the device is as follows: n placing the strip into the machine, it will be carrIed around the uide roller 26 and over the guide rod 27, if t is rod be used, over the pins 20 and over the tablet 7, suitable transfer strips, of course, bein interleaved, and through the feeding mec anism. A control aperture of each strip may be then threaded upon the pin 14 to bring the stri s into registry. One of the strips will be iverted into the record compartment 4 and the other carried outward from the machine and the feed mechanism will then be closed. The turning of the crank 11 operates to feed the combined strips over the tablet by reason first of the engagement of the lug 18 and subsequently by engagement of the discs 8 with the roll 9, which latter engagement continues the strip feed. This feeding action ,"causes the pins 20 to tilt or rotate forwardly with the advancing strips by virtue of engagement in the feed controlling strip apertures. This movement of the pins not only retracts them from aperture engaging position tending thus to release the strips rom the pins, but also moves the pins into forwardly inclined position whereby the positive engagement of the pins in the strip apertures is released, said apertures thus passing from their engaged position over the inclined pins as the strips are forwardly moved. As the next subsequent control aperture comes into registry with the discs 8, the pins 20 project upwardly into the next subsequent set of control aperturesand serve to retard an strip which may have become advanced sllghtly beyond its fellows. At this time, the retarded strips will not have reached quite to the point where they will be released by the feed mechanism, so that the retarded strips will continue to advance while the advance strip is held in stationary position by the pressure of the spring 22.

Just before, however, the handle 11 reaches the stop 12, the lugs 18 will move into a position to come in contact with the strips and the slight continued feeding movement caused thereby will exert suflicient tension upon the pins 20 to start rotation of the shaft 19. Thus 'it will be seen that at the close of the feeding movement, not only is the strip firmly gripped'by the feed to insure that the tearing movement shall not disturb the regis-. tered position of the strips, but also the record forms for the tablet are firmly held under tension between the pins 20 and the feed.

It will be noted that by this construction, the multiple strip may behandled as a unit in threading the machine, excepting for the interleaving of the carbons, and thus one of the great inconveniences in using this type of machine is avoided.

Thus by the above construction are accomplished many others than the objects here1nbefore set forth. I

Since certain changes may be made inthe above construction and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawingsshdll be interpreted as i].-
